With respect to partic ular circumstances, local, state, and federal laws and regulations should be reviewed. API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or fed erallaws. Information concerning safety and health risks and proper precautions with respect to par ticular materials and conditions should be obtained from the employer, the manufacturer or supplier of that material, or the material safety data sheet. Nothing contained in any API publication is to be constmed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or prod uct covered by letters patent. Neither should anything contained in the publication be con strued as insuring anyone against liability for infringement of letters patent. Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. Sometimes a one-time extension of up to two years will be added to this review cycle. This publication will no longer be in effect five years after its publication date as an operative API standard or, where an extension has been granted, upon republication. Status of the publication can be ascertained from the API Downstream Segment [telephone (202) 682-8000]. A catalog of API publications and materials is published annually and updated quarterly by API, 1220 L Street, N.W., Washington, D.C. 20005. This document was produced under API standardization procedures that ensure appropri ate notification and participation in the developmental process and is designated as an API standard. Questions concerning the interpretation of the content of this standard or com ments and questions concerning the procedures under which this standard was developed should be directed in writing to the standardization manager, American Petroleum Institute, 1220 L Street, N.W., Washington, D.C. 20005. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the gen eral manager. API standards are published to facilitate the broad availability of proven, sound engineer ing and operating practices. These standards are not intended to obviate the need for apply ing sound engineering judgment regarding when and where these standards should be utilized. The formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices. Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard. API does not represent, warrant, or guarantee that such prod ucts do in fact conform to the applicable API standard. All rights reserved.

Copyright © 200] American Petroleum Institute FOREWORD This standard provides minimum requirements for the design and constmction of installa tions for the storage and handling of liquefied petroleum gas (LPG) at marine and pipeline terminals, natural gas processing plants, refineries, petrochemical plants, and tank farms. This standard takes into consideration the specialized training and experience of operating personnel in the type of installation discussed. In certain instances, exception to standard practices are noted and alternative methods are described. This standard does not include information on the production or use of liquefied petro leum gas. h is not intended that this standard be retroactive or that it take precedence over contrac tual agreements. Wherever practicable, existing codes and manuals have been used in the preparation of this standard. This standard requires the purchaser to specify certain details and features. Although it is recognized that the purchaser may desire to modify, delete, or amplify sections of the stan dard, it is strongly recommended that such modifications, deletions, and amplifications be made by supplementing this standard rather than by rewriting or incorporating sections of this standard into another complete standard. API standards are published as an aid to procurement of standardized equipment and materials. These standards are not intended to inhibit purchasers or producers from purchas ing or producing products made to specifications other than those of API. API publications may be used by anyone desiring to do so. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any federal, state, or municipal regulation with which this publication may conflict. Suggested revisions are invited and should be submitted to the standardization manager, American Petroleum Institute, 1220 L Street, N.W., Washington, D.C. 20005. iii CONTENTS Page SCOPE .............................................................. 1.6 Retroactivity ..................................................... 1.7 Characteristics of LPG ............................................. 1.8 Safety .......................................................... 2 REFERENCED PUBLICATIONS ........................................ 3 TERMS AND DEFINITIONS ............................................ 2 4 DESIGN OF LPG VESSELS ............................................. 3 4.1 Applicable Design Construction Codes ... .. 3 4.2 Design Pressure and Temperature. .. 3 4.3 Design Vacuum ................................................... 3 4.4 Materials of Construction ........................................... 3 4.5 Vessel Connections ................................................ 3 4.6 Previously Constructed Vessels ....................................... 3 5 SITTING REQUIREMENTS AND SPILL CONTAINMENT. .................. 3 5.1 Siting ........................................................... 3 5.2 Drainage ......................................................... 5 5.3 Spill Containment ................................................. 5 5.4 Remote Impoundment .............................................. 5 5.5 Diking ........................................................... 6 6 FOUNDATIONS AND SUPPORTS FOR LPG STORAGE VESSELS AND RELATED PIPING ................................................ 6 6.1 Applicable Codes and Specifications .................................. 6 6.2 Special Requirements .............................................. 6 7 TANK ACCESSORIES, INCLUDING PRESSURE AND VACUUM-RELIEVING DEVICES ....................................... 8 7.1 Mandatory Equipment. .. 8 7.2 Tank Accessory Materials. .. 10 8 PIPING REQUIREMENTS ............................................. 10 8.1 American Society of Mechanical Engineers Code for Pressure Piping. .. 10 8.2 LPG Piping ...................................................... 10 8.3 Fittings.. .. 10 8.4 Plugs..... .. 10 8.5 Unions... ..
